Free why java is platform independent software for linux

Platform Independent Petri Net Editor project (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively.

A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations.

Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification.

PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.

Sun Java Platform Enterprise Edition (Java EE) is the industry standard for developing portable, robust, scalable, and secure server-side Java applications.

Building on the solid foundation of Java SE, Java EE provides Web services, component model, management, and communications APIs that make it the industry standard for implementing enterprise class service-oriented architecture (SOA) and Web 2.0 applications.

iFTPd, Independent FTP Daemon, is an open source FTP server written in Java. Independent FTP Daemon features platform independence, system independence, ruggedness and a virtual file system.
The target audience of the FTP server is for those admins that need to be able to share files without having to install several other programs and databases and without having to configure the rest of the system.
Main features:
- Platform independence (Where do you want your JVM to go today?)
- System independence
- Does not require any users / groups on the host system.
- Does not require an SQL database.
- Does not does have weird and wonderful dependencies that must be downloaded from 500 different places.
- Ruggedness
- Once started, only the admin can stop iFTPd
- Virtual file system
- Create virtual file links, virtual directory links
- Merge several directories into one virtual directory
- Completely transparent to the user
- Users and groups

- Multithreading
- Text file-based configuration
- Telnet-based status monitor
- HTML status monitor
Installation:
Unpack iftpd.zip.
Check that conf/iftpd.conf is to your liking.
Make at least one group in conf/groups/.
Make sure that at least one of the groups has a root directory.
"/stash/ftp/" r+ "/"
Make at least one user file in conf/users/.
Start iFTPd.
Linux users run: iftpd.sh
Enhancements:
- SSL (AUTH TLS) support has been added.

Java Parallel Processing Framework is a set of tools and APIs to facilitate the parallelization of CPU intensive applications, and distribute their execution over a network of heterogenous nodes.
Java Parallel Processing Framework is intended to run in clusters and grids.
Main features:
- an API to delegate the processing of parallelized tasks to local and remote execution services
- a set of APIs and user interface tools to administrate and monitor execution services
- real-time adaptive load balancing capabilities
- scalability up to an arbitrary number of processing nodes
- support for failover and recovery
- limited intrusiveness for existing or legacy code
- a dynamic deployment mechanism, that enables the execution of new, or updated, code without having to deploy onto the grid
- fully documented APIs, administration guide and developer guide
- runs on any platform supporting Java 2 Platform Standard Edition 5.0 (J2SE 1.5)
Enhancements:
- JPPF is now licensed under the terms of the Apache License, Version 2.0. Starting from JPPF 1.0 beta1, all releases will be licensed under these terms.
- Prior versions will remain under the terms of the LGPL.
- For the first time, JPPF integrates seamlessly with J2EE. The JPPF Resource Adapter provides J2EE application servers with an access to native grid services.
- Numerous bug fixes, especially with regards to the distributed class loading mechanism.

Java 2SE technology readily harnesses the power of the network because it is both a programming language and a selection of specialized platforms.
As such, it standardizes the development and deployment of the kind of secure, portable, reliable, and scalable applications required by the networked economy.
Because the Internet and World Wide Web play a major role in new business development, consistent and widely supported standards are critical to growth and success.
The Java programming language lets you write powerful, enterprise-worthy programs that run in the browser, from the desktop, on a server, or on a consumer device. Java programs are run on -- interpreted by -- another program called the Java Virtual Machine (Java VM).
Rather than running directly on the native operating system, the program is interpreted by the Java VM for the native operating system. This means that any computer system with the Java VM installed can run a Java program regardless of the computer system on which the application was originally developed.
The Java platform is a software-only platform that runs on top of other hardware-based platforms. Because hardware-based platforms vary in their storage, memory, network connection, and computing power capabilities, specialized Java platforms are available to address applications development for and deployment to those different environments.
Java technology has grown to include the portfolio of specialized platforms listed below. Each platform is based on a Java VM that has been ported to the target hardware environment. This means, for example, in the case of Desktop Java, desktop applications written in the Java programming language can run on any Java VM-enabled desktop without modification.
Java 2 Platform, Standard Edition (J2SE), provides an environment for Core Java and Desktop Java applications development, and is the basis for Java 2 Platform, Enterprise Edition (J2EE) and Java Web Services technologies. It has the compiler, tools, runtimes, and Java APIs that let you write, test, deploy, and run applets and applications.
Enhancements:
- Olson time zone data was updated to version 2007e.
- Solaris-specific I/O interruption in response to thread interruption can now be switched off.
- Many bugs were fixed.

Caffeine is a free high-performing interoperability solution between the Java platform and the .NET framework.
Caffeines key differentiator is that does not replace the Java Virtual Machine. Instead, your JVM of choice is hosted within the .NET runtime, ensuring that vendor-specific VM optimizations are preserved.
The specific objectives of Caffeine are:
- Run on any combination of .NET runtime (1.0+) and Java Virtual Machine (1.2+).
- Allow full reuse of any Java library from a .NET environment, working exclusively at the API level and avoiding bytecode translation of the actual implementation.
- Provide optimal performance, running the JVM and .NET under the same process and avoiding network or IPC costs.
Caffeine is open source, built for and by developers, and licensed under an MIT/X license that allows Caffeine to be used and/or embedded in commercial software.
Main features:
- Bindings of jobject, jarray, jvalue, jclass, jmethoid, jclassid, jfieldid.
- C# wrapper class generator toolchain from Java library.
- Public and protected classes and methods.
- Inner types, within classes and interfaces.
- Abstract classes and interfaces.
- Object casting.
- Arrays.
- Constants in interfaces.
- Basic temporary interoperability between System.String and java.lang.String.

Ambisonics Player is a simple player for ambisonics files. Ambisonics Player is programmed in Java, which means that (in theory) should be able to run on all platforms that java runs on. Java-sound must also be implemented on the platform.
It has been developed on Windows XP running Java 1.5, and also tested on linux 64-bit system (Gentoo AMD64) using sun-jdk-1.5.0.03. So these combinations should be fine. I dont think it works with earlier java-versions than 1.5, atleast not very good.
Main features:
- Plays 1.,2. and 3. order soundfiles in B-format.
- Files in wav,aiff,flac and ogg format supported (ogg-files caneven be streamed).
- Floating point support (for WAV-files only).
- Decode ambisonics to speaker-feeds or binaural stereo files by using HRTF and decode to virtual speaker-array.
- Play directly to soundcard outputs or save to file.
